Hi. I am 40 year old female with diabetes but my sugar levels are under control. I have other complaints like hypertension, arthritis and spondylosis etc. My medication includes glycomet gp-1 2 per day, metoprolol xr 50 mg in morning, shelcal ct 500 mg, evion lc and night time aceclo plus for pains. My complaint is I have pain my left leg muscle under knee and it won't allow me to sleep in nights. It's squeezing during night as I lie in the bed. Can you suggest reason and medication.
